Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169628, here are decompositions:

37 + 169591 = 169628
61 + 169567 = 169628
97 + 169531 = 169628
127 + 169501 = 169628
139 + 169489 = 169628
157 + 169471 = 169628
229 + 169399 = 169628
307 + 169321 = 169628

Showing the first eight; more decompositions exist.
